摘要:
The invention relates to a process for preparing a substrate with a multizone metallic coating comprising the steps of heating a metallic material optionally comprising a metallic outer layer having a different composition than said metallic material, to a temperature T1, depositing a coating of aluminium, magnesium, and/or zinc, and cooling down to a temperature T2 and continuing the deposition. It furthermore relates to a substrate with a multizone metallic coating obtainable with said process.
摘要:
The present invention is directed to processes and devices for performing the processes comprising electroplating one or more metallic or non-metallic continuous products with metals or metal alloys in a continuous process from aprotic electrolytes free of water and oxygen, wherein the continuous product is passed through a lock system (1) into an encapsulated coating plant under inert gas atmosphere, and the following steps are performed at temperatures ≦120° C.: activating the continuous product to be coated; rinsing the continuous product to be coated; contacting the continuous product to be coated; electroplating the continuous product to be coated using a metal or metal alloy; drying the coated continuous product; discharge of the coated continuous product from the plant through a lock system.
